I’d like to travese the contents of an xml.collected() in a reverse order. I have for connectionFromXML in xml.collected(viewFromXML,"/connection") do parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML) end I tried: local relationTable = xml.collected(viewFromXML,"/connection") for i=#relationTable, 1, -1 do connectionFromXML = relationTable[i] parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML) end But apparently my lua knowledge is lacking (severely, I might say) as this ends with “attempt to get length of a function value “ What is the correct way to do it?

it's an iterator

What is the correct way to do it? xml.all

Tried to find documentation, but failed. Tried this: local relationTable = xml.all(viewFromXML,"/connection") for i=#relationTable, 1, -1 do connectionFromXML = relationTable[i] parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML) end but it fails as well. G

xml.all

It had been awhile, so for the record. I was looking for something similar and found out that adding a third argument to the xml.collected reverses the iterations. Looks like the argument has to be true in a boolean sense, so puting any "string" there will do the trick. for v in xml.collected(doc, "/chapter/section", "string") do ... end Jano
